In this study, the scientific validation of different organic preparations like amritpani, panchagavya, vermiwash and Jeevamrita in terms of microbial population and their activity has been performed. Microbes isolated from these preparations were tested for plant growth promoting (PGP) properties and finally characterized by biochemical and molecular tools. Strains of Bacilluspumilus and other bacillus sp. isolated form panchagavya showed positive results for HCN and ammonia production while bacteria isolated from vermiwash (Bacilluspumilus and Brevibacteriumlaterosporus) showed positive results for HCN production and P-solubilization. Plant growth promoting strain Brevibacillusborstelensis (isolated from amritpani) showed positive results for all PGP properties (including HCN, siderophore, ammonia, catalase and IAA production) except
P-solubilisation. Based on these PGPR properties, such strains can be utilised for development of microbial consortia and other bio-formulations for sustainable agriculture production.
